[2] The costliest tropical cyclone was Hurricane Helene, with a damage total of at least $78.7 billion, most of which occurred in the Southeastern United States.

Meanwhile, the deadliest tropical cyclone was Typhoon Yagi, which caused at least 844 fatalities in Southeast Asia (particularly Myanmar, Vietnam, Thailand and the Philippines) and South China.

After the New Year, the Madden–Julian oscillation's (MJO) amplitude weakened, with its eastward propagation slowing down due to the positive phase of the Indian Ocean Dipole (IOD) and an equatorial Rossby wave.

Showers and thunderstorms within the disturbance became better-organized beginning late the following day, and Tropical Depression 01E formed during the morning of July 4.

[47][48] In late October, Hurricane Kristy formed off the coast of southern Mexico, in-part from the remnants of Atlantic basin Tropical Storm Nadine, and intensified to Category 5 strength out in the open ocean.

It began to move over the warm tropical waters of Lamon Bay, where the JTWC and the JMA upgraded Ewiniar into a minimal typhoon.

Being in a favorable environment in the Philippine Sea, Gaemi continues to strengthen into a severe tropical storm as it moves northeastward slowly.

The next day, Gaemi made its final landfall at Xiuyu, Putian at Fujian Province as a weakening tropical storm.

The following day, it rapidly intensified, developing a distinct eye and briefly reaching Category 5-equivalent super typhoon status as it approached Hainan.

On September 7, Yagi underwent a period of reorganization and regained Category 4 status before making a historic landfall between Haiphong and Quang Ninh in Vietnam.

While Yagi was on its way to making landfall in the Philippines, JTWC announced another formation of a tropical disturbance in the open Pacific Ocean on September 2.

As Bebinca moved toward eastern China, two tropical depressions formed in the Pacific on September 15—one near Guam and another within the Philippine Area of Responsibility (PAR).

The following day, Trami emerged above the coastal waters of southern Ilocos Sur, leaving the remnants of a circulation center over Northern Luzon.

Shortly after reaching its peak intensity, Kong-rey started to slightly weaken as it went through eyewall replacement cycle moving northwestwards.

Owing to favorable conditions and high Sea surface temperature over Northern Bay of Bengal, the depression intensified into a cyclone named Remal.

On November 23, a low pressure area formed over east equatorial Indian ocean and south-east Bay of Bengal.

[61] Severe Tropical Storm Eleanor formed on 17 February, bringing intense rainfall and winds causing massive damage.

[64] Short-lived Tropical Cyclone Gamane emerged on 25 March, causing a total of 19 deaths, 3 people missing and at least 90,000 affected.

Another off-season, Tropical Cyclone Ialy, formed on 16 May near Comoros, killing a girl and injuring four others, while another person died due to a fallen wall.

[70] Severe Tropical Cyclone Neville formed north of the Cocos Islands[71] on 1 March and left the basin 20 days later.

[81] After the system exited to the Australian region and struggled against moderate wind shear, 05F re-entered on February 7 and JTWC designated it tropical storm 12P.

The FMS upgraded Nat to a Category 2 tropical cyclone the next day before wind shear led to the system's demise.

In the early hours of December 15, 2024, Subtropical Storm Biguá formed off the coast of the Brazilian state of Rio Grande do Sul, according to CHM.

[89] Tropical Storm Alvaro from the South-West Indian Ocean persisted into 2024 and made landfall in Madagascar, killing nineteen and causing some damages.

On the last day of April, Cyclone Hidaya formed near Seychelles and made a rare landfall in Tanzania as a weakening tropical storm.

Beryl entered the Caribbean Sea, and strengthened further into a Category 5 major hurricane, becoming the strongest tropical cyclone of this month.

In the Eastern Pacific, short-lived Tropical Storm Bud unexpectedly formed off the southern tip of Baja California.

It then traversed through the Leeward Islands and Puerto Rico as a tropical storm and made landfall in Bermuda as a Category 1 hurricane.

Hurricanes Isaac and Kirk, Typhoon Krathon and tropical storms Jebi and Joyce also developed in the succeeding days.

A day after Dana was named, Typhoon Kong-rey formed in the Western Pacific; initially located southeast of Guam, the storm later passed through Batanes before it made landfall in Chenggong, Taitung in Taiwan.
